Its signal correlation as well as minimal distance is determined by modulation index κ which also roughly corresponds to the occupied bandwidth [20].
Bottom - Left panel: LFP phase-amplitude coupling (measured by Modulation Index) for pairs of frequencies during rest, showing peak in theta gamma pairs.
As to the NYFR output signal parameter estimation steps, the existing algorithm constructs a multi-channel architecture to remove the LOS modulation by estimating the NZ index through extracting frequency domain feature for each channel firstly and then estimates other parameters using conventional methods [8, 11].
In active vision, however, the visual system can make use of an internally generated signal, which is the saccade-related brief excitability modulation indexed by LFP changes.
We consider happy and angry facial emotion since we have previously reported consistent effects of N170 amplitude modulation indexed by those both emotions [ 36, 37] Opposed valence words controlled for arousal, content, length and frequencies were also selected from a dataset reported in other study [ 31].
This was represented by a "modulation index" (MI), calculated as the total activity during SN as a proportion of total SD + SN activity.
Furthermore, it should be pointed out that the serotonergic (as indexed by 5HTTLPR genotype) modulation of risk-taking behavior is dissociated from the dopaminergic modulation (as indexed by a trend-level effect of DAT1 genotype).
The RMS output voltage of the H-bridge can be varied by changing the modulation index, M. The conventional PI controller is employed to adjust the equivalent modulation index.
This problem is well demonstrated, for example, by QPSK and complex-orthonormal QFSK (modulation index κ = 1) modulation with XOR (5).
An infinite variety of CPM signals can be generated by choosing different pulse shapes g(t) and by varying the modulation index h and alphabet size M.
